Privacy Policy

Last updated: 2 October 2026

This policy explains what personal information the Maths Mama mobile app and this website (mathsmamasurajsir.com) collect, why we collect it, who we share it with, how long we keep it, and what choices you have. We have tried to keep it short and in plain English.

1. Who we are

Maths Mama is an online maths coaching app for students of Class 11 and Class 12, run by Maths Mama Edtech, India ("we", "us", "our"). We are the party that decides how your personal information in the app and on this website is used.

2. What we collect, and why

What	Details	Why we need it
Account details	Your name, email address and mobile number, which you type in when you sign up.	To create and run your account, to send your login code by email, and to contact you about your classes. Your phone number is not verified and we do not send you SMS or WhatsApp codes.
Login and session data	The one-time email code (kept only in scrambled, hashed form and valid for 5 minutes); login tokens that keep you signed in (kept hashed, valid for 30 days); a random device ID the app creates on your phone; the app version and phone platform (Android or iOS).	To let you in securely, keep you signed in, and prevent misuse.
Course access	Which courses or levels you can open (for example Class 11 or 12, Board, JEE Main, JEE Advanced), the start and end dates of your access, and any note our team adds when granting access.	To unlock the right content for you.
Tests (CBT)	Your answers, questions you flagged, time spent on each question, when you started and submitted, your marks, accuracy, rank and percentile, the app version and device ID, and the IP address you used while taking the test.	To run timed tests, save your answers, mark them, show your results and rank, and keep tests fair and secure.
Doubts	The questions you type, any photos you attach, the chapter you chose, times, and the replies from our teachers.	To answer your doubts. Photos are stored in private storage and shown only through short-lived links.
Parent-teacher meetings	Whether you were invited to a meeting, and the meeting link we shared.	To invite you and send reminders.
Notifications	An identifier that links your device to your Maths Mama account so our notification providers can deliver push notifications to it (see section 5). We do not store your phone's push token ourselves.	To tell you about doubt replies, meetings and other class updates. You can switch notifications off in your phone settings.
Videos	When you play a lecture, our server checks that you have access and issues a short-lived signed link. A slowly moving watermark showing your phone number (or email if there is no phone number) is drawn over the video. On Android the app blocks screenshots and screen recording.	To deliver video only to students who have access, and to discourage piracy of our lectures.
Course access records	Which courses our team has given you access to, the dates of that access, and any reference our team records for it. The app does not sell anything and never asks for card, bank or UPI details.	To give you access and to keep accounting and tax records.
Messages to us	What you send us by email or WhatsApp, and your contact details.	To reply and support you.
Technical logs	Our servers keep technical logs of requests, which can include your IP address (for example when too many login codes are requested). Logs are rotated automatically.	To keep the service secure, stop abuse and fix errors.

On your phone. Your login tokens are kept in your phone's secure storage. While you take a test, your answers are also saved on the phone so the test can continue if your internet drops; this saved test data and your session are cleared when you log out. The app asks for camera or photo access only when you choose to attach a photo to a doubt. It does not use your location, contacts or microphone.

What we do not collect. We do not collect card or bank details, your location, your contacts, or your government ID numbers. The app contains no advertising SDKs and no separate analytics or crash-reporting SDKs.

3. How login works

Students do not need a password. You enter your email address, we email you a six-digit code, and you type it into the app. The code works once, expires after 5 minutes, and is locked after too many wrong attempts. You can also type your phone number as your login name; the code is still sent to the email address on that account. Your mobile number is collected at sign-up only so that we can contact you. We do not verify it and we do not send codes to it.

4. How we use your information

• To create your account, log you in, and give you the courses you have access to.
• To run tests, mark them, and show results, rank and percentile.
• To answer your doubts and run parent-teacher meetings.
• To send service messages: login codes, doubt replies, meeting reminders and important updates.
• To keep the service secure, prevent misuse and piracy, and fix problems.
• To keep accounting records and meet our legal obligations.

We do not use your information for advertising, we do not build advertising profiles, and we do not make automated decisions about you.

5. Who we share information with

We do not sell or rent your personal information. We use the following service providers to run Maths Mama. They receive only what they need to do their job.

Provider	What it does for us	What it receives
Amazon Web Services (AWS)	Cloud servers that run the app's backend, and private file storage (Amazon S3) for images such as doubt photos.	Account and activity data described in section 2, and the photos you attach to doubts.
Cloudflare	Sits in front of our servers to route traffic and protect against attacks, and hosts this website.	Normal web traffic details such as your IP address.
Email delivery service (Amazon SES)	Sends your login code and other service emails.	Your email address and the email content.
Bunny.net	Stores and streams our lecture videos.	Your device requests the video with a short-lived signed link, so Bunny.net sees the usual connection details such as your IP address.
OneSignal	Delivers push notifications.	Your Maths Mama account ID and your device's notification registration, plus the text of each notification.
Google Firebase Cloud Messaging	Delivers push notifications on Android phones.	Your device's notification registration.
Google Play and Apple App Store	Distribute the app.	Whatever you share with them when you install or update the app, under their own privacy policies.
WhatsApp (Meta)	Only if you choose to message us on WhatsApp.	Your messages and phone number, under WhatsApp's own policy.

Our own team. Teachers and administrators at Maths Mama Edtech can see your account details, course access, test results and doubts so that they can teach and support you.

Other disclosures. We may disclose information if the law, a court or a government authority requires it, or to protect our users and our service from fraud or harm. If Maths Mama Edtech is ever sold or merged, your information may move to the new owner, who must honour this policy.

Where data is processed. Some of the providers above are global companies, so your information may be processed on servers outside India.

6. Our website

Our website uses cookies and similar tools. It uses Google Analytics and Microsoft Clarity to understand how visitors use the site, the Meta (Facebook) Pixel to measure our own marketing, and Google Fonts to display text. A WhatsApp chat button lets you start a chat with us. These tools may set cookies and collect your IP address, device and browsing information. You can block or delete cookies in your browser settings. These tools are on the website only; they are not in the app.

7. Children and age

Maths Mama is made for students in Class 11 and Class 12 and is intended for people aged 13 and over. We do not knowingly collect personal information from children under 13 and we do not target them. If you are under 18, please use the app with the knowledge of a parent or guardian. If you are a parent or guardian and believe a child under 13 has given us information, or you would like to see, correct or delete your child's information, email us at mathsmamaedtech@gmail.com and we will act promptly.

8. How long we keep information

• Your account, test results and doubts: for as long as your account exists. When you delete your account, they are deleted (see section 10).
• Login codes: valid for 5 minutes.
• Login sessions: valid for 30 days; expired sessions are purged automatically.
• Detailed answer-saving records from tests: deleted automatically after 90 days.
• Photos you start to attach but never send: deleted automatically after 24 hours.
• Course access and accounting records: kept for as long as Indian accounting and tax law requires. After you delete your account, they are kept without your name, email address or phone number.
• Sign-up block record: after you delete your account we keep a one-way, keyed fingerprint of your email address and phone number (it cannot be turned back into them), so that the same email address or phone number cannot be used to sign up again and misuse free trials. If you want to use them again, email us.
• Technical logs: rotated automatically.

9. How we protect your information

• The app talks to our servers over encrypted HTTPS connections.
• Login codes and login tokens are stored only in scrambled (hashed) form. Codes are rate-limited and expire quickly.
• On your phone, login tokens are kept in the phone's secure storage.
• Photos and PDFs are kept in private storage and opened only through short-lived links. Videos use short-lived signed links.
• Only authorised team members can reach the admin tools.
• Our server software is kept up to date and automatically scanned for known security problems.

No system is perfectly secure. If you think your account has been misused, email us straight away.

10. Deleting your account

You can delete your account at any time:

• In the app: Profile, then Delete account, then type DELETE to confirm. This takes effect immediately.
• By email: write to mathsmamaedtech@gmail.com from the email address you registered with, with the subject "Delete my account". We act within 7 days and confirm by email.

Full details are on our Delete your account page. In short:

• Deleted: your profile (your name, email and phone number are removed and replaced with "Deleted user"), your test attempts, answers and results, your doubts with their messages and photos, your login sessions and codes, your notification registrations, and your meeting invitations.
• Kept: course-access and accounting records that we need to keep by law. They are kept without your name, email address or phone number, and are linked only to an internal account number.
• Also kept: a one-way, keyed fingerprint of your email address and phone number (it cannot be turned back into them). This stops the same email address or phone number from being used to sign up again. If you want to use them again, email us.
• You are signed out everywhere straight away.

11. Your rights and choices

You can ask us at any time to:

• tell you what personal information we hold about you and give you a copy;
• correct information that is wrong or out of date;
• delete your information (or delete your account yourself, as described above);
• stop sending you notifications (you can also switch them off in your phone settings);
• withdraw any consent you have given us.

These are rights you have under Indian law, including the Digital Personal Data Protection Act, 2023. To use any of them, or to make a complaint, email mathsmamaedtech@gmail.com. We may need to confirm that the request really comes from you. If you are not satisfied with our response, you may also complain to the authority that Indian law provides for this.

12. Changes to this policy

If we change this policy we will update the "Last updated" date at the top of this page, and for important changes we will also tell you in the app or by email.
